Average Moisture Content - an overview ScienceDirect Topics

The average moisture content of the five lithotypes in coal samples from five localities in the Latrobe Valley are given in Table 2.2.Some variation in moisture content occurs between the lithotypes but the range is relatively small within an unexposed seam (generally 2 to 3%, and at most, 5%).
